Where to get the Playdom Game Card?

Can anybody tell me where to get this Playdom Game Card?
I am playing Social City and improving to the next level.
I want to be the successful Mayor of Syzn City.
There are said that this card is available in 7 Eleven...but is it true?
I tried to ask the nearest & Eleven here but they sell only the MOL Point.
I don't need MOL Point. I want Playdom Card.

This is the card.

And this is my city!
